The following map is from the World Dental Federation. This map shows the incidence rate per 100,000 people of oral and lip cancer in individuals who are 15 years of age and older. Based on this map, the U.S. appears to have an oral cancer incidence rate of 5.0 – 6.9 per 100,000 people. This incidence rate is higher than other countries, which aren’t as developed or economically stable. Maps like this are important in understanding the differences in incidence and prevalence rates of many oral health-related issues.

The iceberg, called B-15, has been drifting away from Antartica for around 20 years, covering more than 6,600 miles. The iceberg has gradually fractured into multiple smaller sections, and the section pictured is called B-15Z.

This map tracks the course of B-15Z over time, and the iceberg is now passing the South Georgian Islands. The iceberg is nearing the equator, and the warmer tropical waters will quickly melt away the gargantuan ice mass,

Air pollution is definitely a concern, especially with the growing population. I came across this air pollution map on aqicn.org that shows real-time air quality around the world. The screenshot below is of the United States, and shows that earlier today, we had a good to moderate air pollution level. If you check out the site, you can see a map of the world and compare how each country or continent is ranking in their current air level rate. The map is color-coded with green being good, yellow being moderate, orange is unhealthy for sensitive groups, red is unhealthy, purple is very unhealthy and dark red is hazardous.

Check out what your area looks like, and keep in mind how you can lessen your amount of air pollution! Check out the site by going to aqicn.org or click here.
